h1. An example of working port-forwarding configuration h2. (Paraphrased from description by Brian J. Gibbens) For those interested, this is how I set up Leginon on the TF20 in the Kornberg lab at Stanford with the following configuration: Local network (192.168.xxx.xxx in this example) can not be accessed directly through building network that has internet access before port forwarding. # TECNAI_COMPUTER (Windows XP) not connected to network, but connected directly to Tecnai F20 and to TF20SUPPORT_COMPUTER (Windows XP) through two separate network cards. Static local IP addresses (192.128.xxx.xxx (168.128.xxx.xxx in this example) should be set on these. Local IP address of the TF20SUPPORT_COMPUTER 192.168.200.100 168.128.200.100 in the example figure) was added to the TCP/IP settings on the network on the TECNAI_COMPUTER that connects to the TF20SUPPORT_COMPUTER. !gateway.png! # TF20SUPPORT_COMPUTER has two network cards and two IP addresses. One is connected to building network, the other is connected to the TECNAI_COMPUTER as mentioned above. # WEBSERVER_DATABASE_COMPUTER (Suse 11.1 Linux) with MySQL, PHP, and Samba share for drive mapping on PC's. Connects to TF20SUPPORT_COMPUTER through building network. !http://emg.nysbc.org/attachments/2484/PortForward.png! --Norton firewall settings on TF20SUPPORT_COMPUTER configured to allow communication to both '1' and '3'. --Appropriate IP addresses and hostnames added to the hosts files (C:/WINDOWS/System32/drivers/etc/hosts.txt on Windows PC's and /etc/hosts on Linux). '2' and '3' listed in hosts file on '1'; '1' and '3' listed in hosts file on '2'; and '2' only listed in hosts file on '3' since all communication from '1' to '3' through '2' will appear to come from '2'. --Program for port forwarding (AUTAPF) installed on TF20SUPPORT_COMPUTER and set up to forward all appropriate ports to IP address of the router on TECNAI_COMPUTER that connects to TF20SUPPORT_COMPUTER. Below is a screen shot of how we configured AUTAPF for a test at scripps. The hosts are represented as follows: localdefcon3: the microscope PC running leginon client/launcher defcon3: the support PC with AUTAPF installed amilab7: the remote linux running main leginon !autapf-pfos.PNG! ______ [[Network Configuration| Go up]] ______
